From ed473ebd9c15481669bfcc1058c6b9bba64ecd12 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Tue, 1 Dec 2015 13:47:24 +0800 Subject: [PATCH] ARM: dts: sun9i: Add Reduced Serial Bus controller device node to A80 dtsi This patch adds a device node for the Reduced Serial Bus (RSB) controller and the defacto pinmux setting to the A80 dtsi. Since there is only one possible pinmux setting for RSB, just set it in the dtsi.
